§ 01

Dead pixel and screen defect testing

A full white screen makes it easy to spot dead, stuck or dim pixels on LCD and OLED displays. Set your screen to maximum brightness, go fullscreen, and slowly scan the surface for any dark dots or uneven patches. Repeat with the black screen for stuck-bright pixels.

§ 02

Dust, fingerprints and smudges are much easier to see against a uniformly bright white background.

Screen cleaning on a bright surface

Dust, fingerprints and smudges are much easier to see against a uniformly bright white background. Open the white screen, turn off your room lights, and wipe your display with a microfiber cloth. The bright surface reveals marks you would miss on a normal desktop.

§ 03

Quick webcam and photo fill light

A white screen at full brightness turns any monitor, tablet or phone into a broad fill light. Position the device in front of you for video calls or selfies to soften shadows and improve webcam image quality without extra hardware.

§ 04

Using a white screen as a digital lightbox

Artists and calligraphers use lightboxes to trace designs through paper. A tablet or laptop displaying a full white screen at maximum brightness works the same way — place thin paper over the display and the bright white surface shines through for tracing. Reduce brightness if the light is too intense through the paper.
